I wouldn't say it's not doable. My friend has 1200' with 80' trees on the end. The other end is open. Even though it's super comfortable getting in and out, you only really take off towards the no tree area. 1200' is a lot of runway for a plane that needs 300' to take off and land(in perfect conditions). But 50' trees really make the runway more like 500' or less.

I would say get REALLY used to your plane, practice at the close airport. Put out cones. Find out how short you can actually take off and land. But like the others said, it would be nice if one end was tree less. Your density altitude can make a big difference. The 5's and up need 100HP you see a few 80's around but I think if you talk to them, they all want 100+
